This patch-set resolves several emulator bugs. Each fix is independent of the others. The DR6/7 bug can occur during DR-access exit (regardless to unrestricted mode, MMIO and SPT). Thanks for reviewing the patches, Nadav Nadav Amit (6): KVM: x86: bit-ops emulation ignores offset on 64-bit KVM: x86: Wrong emulation on 'xadd X, X' KVM: x86: Inter privilage level ret emulation is not implemeneted KVM: x86: emulation of dword cmov on long-mode should clear [63:32] KVM: x86: NOP emulation clears (incorrectly) the high 32-bits of RAX KVM: x86: check DR6/7 high-bits are clear only on long-mode arch/x86/kvm/emulate.c | 31 ++++++++++++++++++++----------- arch/x86/kvm/x86.c | 13 +++++++++++-- 2 files changed, 31 insertions(+), 13 deletions(-)
I applied these locally. Can you prepare testcases for patches 1, 2, 4 and 5? Perhaps patch 6 too if it's easy to reproduce.
